Description

  The present invention relates to a method and system for managing user login / logout information independently managed by a service server with a plurality of location servers belonging to a plurality of groups.

  FIG. 1 is a diagram illustrating network connection of user terminals connected to a plurality of service servers according to the conventional invention.

  NHN Corporation, the applicant of the present application, provides a number of online game services such as go-stop, hoora, poker, tetris, and chess through their Hangame site. In FIG. 1, a user using user terminals 101 and 102 connects to game servers 104, 105, and 106 that provide online games that the user terminals 101 and 102 want to play. For example, the game servers 104 and 105 provide a go-stop game service, and the game server 106 provides a fuller game service. At this time, the user login / logout is individually executed by each game server 104, 105, 106, and the user login / logout information is also individually managed by each game server 104, 105, 106. Thus, conventionally, a user who has logged in to one game server knows at all about the current state of the user who has logged in to another game server (for example, whether he / she logged in or logged out, or which game he / she is playing). could not.

  FIG. 2 is a diagram illustrating a network connection between a location server and a service server for managing location information of a conventional user.

  In order to solve the problem of the configuration shown in FIG. 1, in the example of FIG. 2, a location server that can centrally manage user login / logout information in all game servers 204, 205, 206 (Location Server) 207 is provided. When the user connects to the game servers 204, 205, and 206 that provide online games that the user wants to play through the user terminals 201 and 202 and the Internet 103, the game servers 204, 205, and 206 transmit the user login / logout information to the location server 207. To do. As a result, the location server 207 can centrally manage the login / logout information of the users in all the game servers 204, 205, and 206, so that the status of the user who logged in to any server is provided to other users. I can do it now.

  However, currently, online games provided by NHN Corporation are made up of hundreds of game servers. If the management of login / logout information managed by each game server is managed by one location server, there is a problem that the system load on the location server becomes extremely large.

  Such a problem is that when NHN Corporation advances to China and other countries and provides online games, the number of users of online games increases geometrically. If management of logout / logout information is managed by only one location server, there is a problem that login / logout information cannot actually be processed due to an overload problem of the system. In addition to this, it is unavoidable that problems such as hacking and leakage of user information may occur due to inability to properly process user login / logout information. .

  In addition, if the user login / logout information is managed by only one location server, the user log information cannot be updated and managed when the location server does not operate, and the user cannot use the service server. A point is created.

  Therefore, in order to solve the problem of system load concentrated on such location servers, user log information can be managed by using a plurality of location servers belonging to a plurality of location server groups, and belong to the same group. Multiple location servers maintain the same data and state via replication, so that user log information can be managed collectively, and even if one of the multiple location servers does not operate, There is a need for a log information management method and system that can normally manage user log information.

  The present invention has been devised to improve such a conventional technique, and receives log-in / log-out messages from a plurality of service servers while centrally managing user log status information. An object of the present invention is to provide a method and system for reducing the load on a server managing log status information by managing servers managing log status information in a plurality of groups and replicating servers belonging to the same group. To do.

Another object of the present invention is to provide a user log information management method and system capable of managing user log information even when a message is received.

  In addition, the present invention determines a location server group that transmits a log message based on a user identifier, and when a user logs in redundantly, receives a banished message and processes the redundant login state to obtain user log information. It is still another object of the present invention to provide a service server that can not only perform distributed processing but also prevent problems such as leakage of user information and hacking due to duplicate login.

  Further, according to the present invention, it is possible to perform distributed processing of log messages by determining a location server group that transmits log messages according to user identifiers, and the system is overloaded even if the number of users increases geometrically. Still another object of the present invention is to provide a log message distribution device that can stably manage log information without any problem.

  In addition, the present invention allows the location server belonging to the same location server group to hold the same log information so that processing can be performed even if any one location server receives the log message. It is still another object of the present invention to provide a location server that can stably provide a user log service even if one of them does not operate normally.

  In order to achieve the above object and solve the above-mentioned problems of the prior art, a user log information management method according to an embodiment of the present invention includes a step of receiving a login / logout request from a user at a service server.

  Hereinafter, a user log information management method and system according to the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 3 is a diagram illustrating a network connection of a plurality of location server groups including a plurality of location servers according to the present invention, a service server, and a user terminal. Location servers belonging to a location server group need to have the same state information regarding the user's login / logout state.

  The user connects to service servers 304, 305, and 306 that provide online games to be played through the user terminals 301 and 302 and the Internet 303, and selects and inputs login / logout. The service server receives a login / logout request from the user.

  The service servers 304, 305, and 306 send user login / logout messages (external messages) to the location servers 309 among the location servers 309, 310, 311, 312, 313, 314, 315 and 316 belonging to the location groups 307 and 308. Send.

  At this time, if the service servers 304, 305, and 306 send external messages to all location servers instead of one of the location servers 309, 310, 311 and 312 belonging to the location group 307, the number It will be necessary to manage the connection between the hundred service servers and the location server. For this reason, it becomes very difficult to synchronize the status between the location servers 309, 310, 311 and 312 belonging to the location group 307. Therefore, the service server in the present invention transmits the external message to one of the location servers 309, 310, 311, 312 belonging to the location group 307.

  To this end, the service server uses anycast, and the network providing the connection between the service servers 304, 305, 306 and the location servers 309, 310, 311, 312, 313, 314, 315, 316 It is configured to provide anycast capability.

  Each location server 309, 310, 311, 312, 313, 314, 315, 316 is included in any one of a plurality of location groups 307, 308, and the present invention is a plurality of location servers as described above. By classifying and assigning to the location server group, the user log information is distributed and processed.

  That is, when the number of users using the service server increases geometrically, the necessity of such log information distribution processing increases. However, according to the present invention, the number of users using the service server increases. However, the log information of the user can be distributed and processed, and the service provided by the user from the service server can be stably used.

  The user log information processed in each location server group is classified based on the user identifier. For example, when the user identifier starts with “a to h”, the log information of the user is managed in the location server group 1 (reference numeral 307 in FIG. 3), and when the user identifier starts with “iz”, User log information is managed in the location server group 2 (reference numeral 308 in FIG. 3). In addition, although the case where the user identifier was designated by alphabet was illustrated, it is also possible to divide the user identifier by other methods and process each location server group.

  In the present invention, the service servers 304, 305, and 306 determine a location server group that transmits a log message corresponding to the login / logout request based on the user identifier of the user who requested the login / logout.

  For example, when the user corresponding to the user identifier “aaa” selects and inputs login / logout on the service server 304, the location server group 1 (reference numeral 307 in FIG. 3) corresponding to the user identifier is determined (selected).

  The service server 304 transmits a log message to any one location server 309 belonging to the determined location server group 307 by anycast.

  The log message includes the user identifier of the user, the user login / logout status, and the user location information. The user identifier is used to identify a user. For example, a user identifier used for login by a user who logs in / out of the service server is used. The user login / logout state is information regarding whether the user has logged in or logged out. The user location information is information regarding where the user logged in or where the user logged out. The location information is information related to the service server to which the user has logged in / out (service server IP address, service server name, etc.), etc., and the identifier of the service to which the user has logged in / out (for example, “go-stop”, “fuller”). "," Poker ", etc.). When one service provides services on various channels, the location information is a combination of the identifier of the service logged in / logged out by the user and the identifier of the channel logged in / logged out by the user. The location information provides information about where the user has recently logged in or logged out of in the overall service environment.

  The location server 309 that has received the log message processes the log message to generate a status update message. The state update message is transmitted by the location server 309 to other location servers 310, 311, 312 belonging to the location group 307. At this time, the location server 309 transmits the state update message generated by the multicast method to the other location servers 310, 311, and 312. Accordingly, the network providing the connection between the location servers 309, 310, 311, 312 is configured to provide a multicast function.

  In another embodiment, the address of the other location servers 310, 311 and 312 belonging to the location group 307 is stored, and the location server 309 that has received the log message unicasts to each of the other location servers 310, 311, and 312. It is also possible to transmit the status update message using the (unicast) method.

  The location server 309 that has received the log message in this manner generates a status update message corresponding to the log message, and multicasts the status update message generated to the other location servers 310, 311 and 312 belonging to the same location server group. Thus, the status and data of the location servers belonging to the overall location server group 307 are synchronized, and the log information of the users is managed collectively.

  FIG. 4 is a view illustrating a process in which a log message transmitted from a service server according to an embodiment of the present invention is received and processed by a location server belonging to a location server group.

  As shown in FIG. 4, the process of processing the log message in the location server group according to the present invention is as follows.

  In step S401, the service server according to an exemplary embodiment of the present invention receives a login / logout request from a user.

  In step S402, the service server according to an embodiment of the present invention determines a location server group to transmit a log message corresponding to a login / logout request based on the user identifier.

  As described above, the service server can determine the location server group corresponding to the user identifier by holding the user identifier and the location server group identifier corresponding to the user identifier.

  For example, the service server transmits a log message for a user whose user identifier starts with “a to h” to a location server included in the location server group 1, and a log message for a user that starts with “i to z” 2 is configured to be transmitted to the location servers included in 2, and a location server group is determined.

  The log message includes a user identifier of the user, a user login / logout state, and a location identifier related to the location at which the user logged in / out. For example, the log message includes “aaa” as the user identifier, “logout” as the user login / logout state, and “go stop-1” as the location identifier for the position where the user has logged in / out.

  In step S403, the service server transmits the log message by anycast to one location server belonging to the determined location server group. Anycast means that data is transmitted to any one of the constituent elements belonging to a predetermined group. Even if the service server sends the log message to any location server belonging to the determined location server group, the location server that has received the log message transmits the status update message to other location servers belonging to the same group. The location servers belonging to the same group can hold the user log information in the same state.

  In step S404, the location servers belonging to the location server group receive the log message, and in step S405, generate a state update message corresponding to the login message. The status update message is a message including information notifying that the status of the user has been updated from the location server to other servers belonging to the same group, and includes the user identifier of the user, the login / logout status of the user, Contains the location identifier for the logged out location. For example, the log message includes “aaa” as the user identifier, “logout” as the user login / logout state, and “go stop-1” as the location identifier for the position where the user has logged in / out.

  In step S406, the location server multicasts the generated status update message to other location servers belonging to the same location server group. For example, in FIG. 3, when the location server 1 (reference numeral 309 in FIG. 3) receives a log message from the service server, a status update message is generated and other location servers 310, 311, 312 belonging to the same location server group 307 are generated. Send to.

  In FIG. 3, when the location server 5 (reference numeral 313 in FIG. 3) receives a log message from the service server, it generates a status update message and other location servers 314, 315, 316 belonging to the same location server group 308. Send a status update message to.

  In step S407, the location server updates the first user log information stored in the location server based on the generated state update message. The first user log information is user log information stored in a predetermined storage unit based on a state update message generated by the location server itself or a state update message received from another server belonging to the same group. .

  FIG. 6 is a diagram showing a status update message and user log information according to an embodiment of the present invention. As shown in FIG. 6, the status update message 600 includes a user identifier 601, a location identifier 602 regarding a location where the user has logged in / out, and a user login / logout status 603. When the location server receives the status update message 600 while holding the first user log information as indicated by reference numeral 610 in FIG. 6, the location server updates the first user log information as indicated by reference numeral 620 in FIG.

  That is, while the location server holds in the first user log information that the user identifier “aaa” is “GO STOP-1” and in the “LOGIN” state as indicated by reference numeral 610 in FIG. When the state update message 600 indicates that the user identifier “aaa” such as “600” is “GO STOP-1” and is in the “LOGOUT” state, the reference numeral 620 in FIG. 6 is generated based on the state update message. Thus, the first user log information is updated on the assumption that the user identifier “aaa” is “GO STOP-1” and the state is “LOGOUT”.

  Such a user log information update process is performed in the same manner in other location servers in the same group that have received the status update message from the location server. Therefore, each location server belonging to the same group can hold the user log information in the same way, and even if any location server belonging to the same group receives the user's log message, this can be distributedly processed. There is an effect. Further, there is an effect that the log information of the user can be processed normally even if one of the location servers does not operate.

  In step S <b> 408, the location server refers to the updated first user log information and determines whether the user status is a duplicate login status. As a result of the determination, if the login is a duplicate login, an eviction message is transmitted to the service server that transmitted the log message. For example, in the location server, the updated first user log information indicates that the user identifier is “aaa”, the location identifier related to the position where the user has logged in / out is “go stop-1”, and the user's login / logout state is “login” The state update message is generated with the user identifier “aaa”, the position identifier “go stop-2”, and the user state “login”, and the log information of the first user is updated. If this is the case, it is determined that this is a duplicate login state of the user, and an expulsion message is transmitted to the service server that has transmitted the log message, thereby blocking the user connection that has been logged in to "Gostop-2".

  In step S409, the service server receives the banish message and forcibly terminates the connection of the user who has logged in redundantly.

  In step S410, other location servers belonging to the same location group receive the status update message from the location server that received the log message. The status update message is configured as indicated by reference numeral 600 in FIG. The status update message may have the same format as the log message, or may be generated by processing a part of the format. This is also included in the technical idea of the present invention.

  In step S411, another location server belonging to the same location group updates the second user log information stored in the other location server. Since the status update message includes the user identifier, the user login / logout status, and the location identifier related to the location at which the user logged in / out, the other location server sends the other location server to the other location server in response to the status update message. The stored second user log information is updated.

  That is, as described in FIG. 6, the location server uses the user identifier “aaa” as the user log information, “logout” as the user login / logout state, and “go-stop- When the status update message is generated by receiving the log message including “1”, the first user log information for the user “aaa” is changed to “logout” with “go stop-1” based on the generated status update message. Update.

  As another embodiment of the present invention, the location server can manage user information by holding a message buffer instead of user log information. That is, the location server refers to the log message, updates the first message buffer included in the location server, generates a status update message related to the update, and transmits the status update message to the remaining other location servers belonging to the same group.

  At this time, the location server that has received the log message is referred to as a “first location server”, and the remaining other location servers that belong to the same group are referred to as “second location servers”. The location server maintains a message buffer for receiving and storing log messages or status update messages, respectively. The message buffer stores or deletes log messages or status update messages. At this time, the message buffer can also store a part of the format without saving the log message or the status update message as it is. This is also included in the technical idea of the present invention.

  In FIG. 6, while the first location server is saving log messages in the “login” state with the user identifier “aaa” “goa-stop-1” as indicated by reference numeral 610 in FIG. 6 in the first message buffer. In addition, when the log message 600 having the user identifier “aaa” “go-stop-1” and in the “logout” state is received as indicated by reference numeral 600 in FIG. 6, the first location server refers to the received log message 600. To update the first message buffer. That is, if the user status of the message 610 stored in the first message buffer and the received log message 600 are opposite and the user identifier and the location identifier are the same message, the first location server stores the first message buffer. The first message buffer is updated by deleting the message 610 stored in. When the received log message is a message that is in a duplicate login state with the message stored in the first message buffer, the first location server sends an expulsion message to the service server that sent the log message, and the service server Forcibly terminate the connection of the user who has logged in twice.

  The first location server generates a state update message related to the update and transmits it to the remaining second location servers belonging to the same group, so that the state update message is configured as indicated by reference numeral 600 in FIG. The second location server that received the message updates the second message buffer included in each location server, and the location servers belonging to the same group hold the same data and state. The process in which the second location server receiving the update message updates the second message buffer is the same as the first message buffer update process described above.

  Therefore, according to the present invention, location servers belonging to the same group using the user log information or message buffer can hold the same user log information state, and a large number of user log information can be stored while eliminating the overload of the entire system. As a result, it is possible to provide stable management of user log information even if one of the location servers does not operate.

  As another embodiment of the present invention, a log message distribution device that is a network device that receives a log message from a service server and determines a location server group that transmits the log message may be included. The log message distribution device is a network device for reducing a load on a service server by assigning a location server group for transmitting a log message for each user identifier.

  FIG. 5 is a diagram illustrating a network connection of a plurality of location server groups, a service server, and a user terminal, each including a log message distribution apparatus and a plurality of location servers according to another embodiment of the present invention.

  The user connects to service servers 504, 505, and 506 that provide online games to be played through the user terminals 501 and 502 and the Internet 503, and selects and inputs login / logout. The service server receives a login / logout request from the user.

  The service servers 504, 505, and 506 transmit a log message corresponding to the user login / logout request to the log message distribution device 507. The log message distribution device 507 determines location groups 508 and 509 for transmitting log messages corresponding to login / logout requests. Each of the location groups 508 and 509 includes a plurality of location servers 510, 511, 512, 513, 514, 515, 516, and 517.

  The log message distribution device 507 holds one or more group identifiers and user identifier information assigned to each group identifier in a group information database, and user log information processed in each location server group is based on the user identifier. being classified.

  FIG. 7 is a diagram showing an example of a group information database according to an embodiment of the present invention. As shown in FIG. 7, the group information database includes one or more group identifiers 701 and user identifiers 702 assigned to the group identifiers. For example, a user identifier whose user identifier starts with “a to h” is assigned to a group whose group identifier is “1”, and a user identifier which is “i to z” is assigned to a group whose group identifier is “2”. A user identifier starting with is assigned.

  Further, as shown in FIG. 5, when the user identifier of the log message received by the above method starts with “a to h”, the log information of the user is managed in the location server group 1 (reference numeral 508 in FIG. 5). When the user identifier starts with “i-z”, the log information of the user is managed by the location server group 2 (reference numeral 509 in FIG. 5).

  For example, when the user identifier “aaa” selects and inputs login / logout on the service server 504, the service server transmits a log message corresponding to the login / logout request to the log message distribution device 507.

  Since the log message distribution device 507 holds the user identifier included in the log message and the location server group identifier corresponding to the user identifier, the log message distribution device 507 reads (identifies) and reads the user identifier included in the log message. The group identifier assigned with the user identifier is read (identified) and transmitted to the location server included in the group identifier read from the log message. For example, the log message distribution device reads the user identifier “aaa” and the group identifier “location server group 1” to which the identifier is assigned, and stores the log message in the location server 510 included in the location group 1 (reference numeral 508 in FIG. 5). Send to.

  The present invention has an effect of distributing and processing user log information by classifying a plurality of location servers by the log message distribution device 507 and assigning them to location server groups.

  The log message distribution device 507 transmits a log message to any one location server 510 belonging to the determined location server group 508 by anycast. In one embodiment, the log message distribution device 507 transmits the log message to one location server belonging to the same location server group using the round robin method, thereby minimizing the load on the location server group.

  The location server 510 that has received the log message processes the log message to generate a status update message. The status update message is as described with reference to FIG. 6, and the status update message is transmitted by the location server 510 to the other location servers 511, 512, and 513 belonging to the location group 508. At this time, the process in which the location server 510 transmits the status update message to the other location servers 511, 512, and 513 in a multicast manner is the same as the process from step S404 to step S410 in FIG.

  That is, the location server 510 that has received the log message as described above generates a status update message corresponding to the log message, and the status update message generated by the other location servers 511, 512, and 513 belonging to the same location server group.
